Hizb ut-Tahrir is banned in several Central Asian countries and Russia. It seeks to establish an Islamic caliphate, or independent Islamic state, in Central Asia. It claims to be a moderate, nonviolent organization. However, two political groups that have their origins in Hizb ut-Tahrir -- Hizb-an-Nusra and Akrimiya -- do have more radical platforms.

Thousands of Hizb ut-Tahrir members and supporters have been arrested and imprisoned for alleged extremist activities in Central Asia and Russia.
